To be clear: The hashtable actually uses a bit different algorithm. The
hash code is used to determine t

You can get dupes with GetHashCode(); but two objects with the
same "value" must have the same hash code.
I'll admit that Equals() must be overridden when GetHashCode() is
overridden; but, I disagree that GetHashCode() is used wherever Equals()
is used.
As with any hash, objects of save "value" *

Why? you can also get dupes with GetHashCode. It's not as if it's a
magic value.
There's been some discussion lately regarding the Object.GetHashCode()
method.
I think the concensus is pretty clear: for best reliability, classes that
implement GetHashCode() should be immutable.
Other than the Hashtable and ProperytCollection classes, does anyone know
where GetHashCode() is us
